This common species may be at once known by its large size, the long, 

 swollen, somewhat flattened, hind tibiae and short tarsi, and by the heavily- 

 speckled fore wings and the heavy lines. The Californian examples do not 

 differ from eastern ones. 



There are two races : one brown-asii, with the wings thickly dusted, 

 while in the other the w ings are clearer and tinged with reddish-brown, while 

 the submarginal row of white dots, with a black dot on the inner side, is quite 

 conspicuous.
